SIGHT FOR GUNS.

Specication of Letters Patent.

Patented Nov. 11,1913.

Application led May 16, 1912. Serial No. 697,616.

To all 'whom t may concern:

Be it known that I, OLoF Boncxnn, a subject of theGrand Duke of Finland and the Emperor of Russia, residing at Berlin-Ivilmersdorf, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Sights for Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates more particularly to sights which automatically adjust themselves within a vertical plane, and the object of the improvements is to provide a sight of this class which is simple in construction and reliable in operation, so that it may be used in hand lire arms to avoid the errors in aiming the gun which are caused when aiming with the gun in inclined position.

lVith this object in view my invention consists in providing rocking supports for the front and rear sights of the gun on the barrel itself and connecting the sights with each other, for example by means of a rod, a tube, or the like, which if required carries a weight adapted to swing within a cavity formed in the frame of the gun.

A further object is to provide means whereby undue oscillation of the pendulum and the sights is avoided when handling the gun. For this purpose I provide the sights with locking means which are thrown into inoperative or nonlocking position when aiming the gun, for example by means of the trigger which when pulled retracts said locking means out of engagement with the sights prior to firing.

For the purpose of explaining the invention an example embodying the same is shown in the accompanying drawing, in which the same letters of reference are used in all the views to indicate corresponding parts.

In said drawings-Figures 1 and 2, are longitudinal sections of the gun taken respectively at the front and rear sights, Figs. 3 and 4f, are cross-sections taken respectively along the lines A-B and C-D of Fig. 1, and Figs. 5 and 6 are detail views showing the locking device for the sight.

Referring to the example illustrated in the drawing, the front sight 71. and the rear sight g are respectively secured to sleeves y' and having a rocking support on outer bushings Z and 7c respectively secured to the barrel o. To reduce friction antifriction rollers a are preferably interposed between the bushings Z, 7c and sleeves j, z'. The said sleeves and rollers are inclosed within dustproof casings consisting of two sections m and a which sections are respectively secured to the frame p and the sleeves i and j and permit oscillation of the sight about the barrel 0. Preferably an insulation is provided between the barrel and the bushings c and Z to avoid objectionable heating of the bearings of the sight.

The sleeves z' and 7' are connected with each other by means of a rod or tube c which as shown in the example illustrated is equipped with a weight 9 having oscillating movement within a cavity d formed in the lower and rear part of the frame p.

The sight is adapted to be locked in position by means of a slide f which is guided in a sleeve s secured to the frame p and is operatively connected with a suitable part of the gun, for example with the trigger u. As shown the slide f is connected with the trigger by means of a link t. The front end of the slide f and the rear end of the rod o are respectively formed with an angular notch and an edge coperating with each other to lock the sight. In the example shown the notch is formed in the slide and the edge on the rod. Normally the slide is in locking position. But when the trigger is pulled, the slide is retracted out of engagement with the rod c during the first part of the movement of the trigger and before firing, so that the sight is free to oscillate and to adjust itself in a vertical plane under the action of the weight 1. The side walls of the angular notch of the slide f provide a guide for the rod c when being retracted, so that undue oscillation of the sight is avoided.

I claim herein as my invention:

1. In a small arm the combination with the barrel, the front sight, and the rear sight, of rocking supports for said sights provided on the barrel and permitting automatic adjustment of the sights within a vertical plane, and means to rigidly connect said sights with each other.
